Title: Novel yarn
IPC: D02G3/40
Filed: 1963-10-18
Abstract: A three-ply composite yarn comprises a bulky stretchable yarn (1)-that is a crimped or knitted one as opposed to a solely elastomeric yarn-of substantially solid structure substantially free from tension, a substantially unstretchable yarn (2) associated with yarn (1) to form a two-ply yarn (3), the stretchable yarn (1) and the substantially unstretchable yarn (2) being aligned substantially parallel to each other or twisted together with a small amount of twist, and a binding yarn (4) helically twisted around the two-ply yarn (3), the yarns (2) and (4) being of the same or different material, and at least one being of polyvinyl alcohol, polyvinyl acetal, rayon, or nylon.  In the many examples given, yarn (1) may be a silk, wool, or rayon acetate yarn crimped by a twisting, steaming, and untwisting treatment; a nylon yarn crimped by false-twisting or stuffer-box crimping, optionally combined when tensioned with an uncrimped nylon or wool yarn, with this composite ply then being relaxed; a blended nylon-wool yarn crimped by a knitting-unknitting treatment; a knit-unknit crimped nylon yarn combined with a false-twisted crimped nylon yarn; a zig-zag crimped metallised polyester foil; weft knitted nylon or wool yarn; knitted material cut into strips and composed of rayon, or crimped nylon and nylon or polyester; a tubular knitted yarn of nylon with a crimped nylon or water soluble yarn core, of wool and polyurethane, of silk, of polyester and crimped nylon, of crimped rayon acetate, of metallised polyester foil, or of heat-set twisted polyester; chain stitched knitted material of nylon, crimped rayon acetate, or nylon and silk; a knitted material of polyacrylonitrile, or metallised polyester foil and nylon or polyester; or a tubular knitted polyester yarn and a polyurethane yarn lightly twisted together and relaxed.  Yarn (2) and/or (4) may be dissolved out of the composite yarn after it has been knitted or woven.  In the examples given yarns (2) and (4) when of nylon may be crimped and tensioned to remove the crimp effect. Yarn (2) if not of the above specified four materials may be composed of wool, cotton, polyester, polyacrylonitrile, metallised polyester foil, or a plied yarn of polyester and rayon or wool.

Title: Valves particularly for use with vessels employed in the brewing and dairy trades
Inventor: BURNETT ALFRED CHARLES
IPC: F16K1/42
Filed: 1959-12-11
Abstract: 909,405. Valves. BURNETT & ROLFE Ltd. Dec. 5, 1960 [Dec. 11, 1959], No. 42245/59. Class 135. A pressure-control valve comprises a cage member 10 supporting an elastomeric sealing ring 6, and a valve member 16 having an inclined surface 24 for engagement with the sealing ring, such engagement being maintained by maintaining at one of the two sides of the closed valve a sufficiently high pressure, such pressure acting on one side of the ring to press it against both its supporting surface and the inclined surface, a gap being provided between the cage and the underside of the valve member so that upon application of pressure at this side to open the valve, this pressure acts on the sealing ring to urge the latter away from the sloping annular surface to facilitate the valve opening. The sealing ring or seat 6 is of a resilient material, such as rubber, and is clamped between the valve housing 1 and the cage 10 by a nut 11, the operative inner end 5 of the seat being, in its unstressed condition, of cylindrical form. The angle of the inclined surface 18 is so chosen that, when the valve member 16 is pulled into the closed position by a knob 21 secured to a stem 20, thereby distorting the cylindrical portion 5, the gripping effect of the latter on the valve member is just sufficient to maintain the valve closed.

As shown a conducting plate 2 forms . one wall of a container, opposite to which is a discharge port 6 covered with a liquid-permeable layer 5. Electrolyte such as a sulphuric acid solution is fed to inlets 1 and discharges through membrane 5 and then flows down the moving aluminium surface while a voltage is applied across the plate 2 as cathode and the aluminium body 8 as anode. The opposite surface of the body 8 may be simultaneously treated by a similar device. In a modification, Fig. 2 (not shown), cooling liquid is projected against the face opposite that being treated. In another modification, Fig. 3 (not shown), pairs of opposed anodizing devices are situated at different levels for the body to move past the pairs in succession and opposed cooling discharge orifices alternate with the pairs of anodizing devices. For treating wire an annular container having its inner surface formed of the liquidpermeable material discharges electrolyte on to a wire moving along the axis thereof Fig. 5 (not shown). Alternatively discharge may be from the outer circumference on to a plurality of moving wires, Fig. 6 (not shown). Using 30 per cent sulphuric acid as the electrolyte maintained at 30C., current densities up to 600 amps/sq.dm. may be used without yellowing of the film. Anodizing  with subsequent cooling of the metal using the apparatus of Fig. 3 produces a cracked oxide film of improved flexibility.
